OCZ Trion 150 480GB SSD review

5. AS SSD benchmark

Review Pages

We move on with the AS SSD benchmark, which contains five synthetic as well as three practical tests. The synthetic tests determine the sequential and the random read / write performance of an SSD. These tests are carried out without using the operating system's cache. The Seq-test measures how long it takes to read and write an 1GB file. Most importantly, this sequential benchmark uses incompressible data for all of its transfers.

During AS SSD the Trion 150 480GB SSD reached a score of 814. Sequential speeds hit 514.7MB/s for reads and 495MB/s write while 4K speeds reached 40.32MB/s for read and 94.45MB/s for write. Access times are for read and write are both 0.031ms and 0.032ms, respectively.

Starting with the read tests, the Trion SSD made it through the sequential read task well and was positioned close to the top of the chart below.

The drive showed exceptional performance in the 4K random read test, leaving many other SSDs behind:

The 4K 64 thread random read test was tougher for the Trion SSD, and it ranked well below the competition:

In the write tests, OCZ' s Trion SSD was very fast at the sequential test (495MB/s) ; it showed a decent performance at the 4K write tests (94.4 MB/s) and fell a bit behind the competition in the 4K random write (64 thread) test:

Next up we ran the Compression Benchmark built-into AS SSD. This test uses a mix of compressible and incompressible data and outputs both Read and Write throughput of the drive.

The Trion 150 480GB SSD showed a stable behavior across the board, save for a very slight dips of a few MB/s in the read test. The compressibility of data being transferred on the SSD had little to no impact on performance.
